单选题When you've read the same paragraph 10 times and you still make little of it as you are reading ancient Egyptian, and you're not studying ancient Egyptian, it's time for you to put the books down. Experts say good breaks are a critical part of exam preparation and actually make your brain work better. Debbie Bruckner, the director of the Student Union Wellness Centre at the University of Calgary, says an overburdened brain stops processing new information. "You've got to put it into your short-term memory and then move it into your long-term memory," she says. To do that, you need to stop cramming new knowledge into your head. Psychologist Joanne Mills says most people can concentrate for 45 minutes to an hour at a time, but then need 15 minutes to rest. She suggests picking your break activity—taking a walk, listening to music—and setting a timer for 15 minutes. "It's a cue to your mind" she says. Mills also suggests setting targets and stopping when you've reached them. "Some students will take that break even if they haven't finished what they set out to do and then they don't really relax or enjoy it because their mind is racing with 'I must, I should, I have to.'" If you're in the flow, ride the momentum until you come to a natural break in the material, then set the timer again and walk to the corner store. Alternating which books you're hitting also helps. Work on English for an hour, then switch to math. It's like exercising multiple muscles at the gym, as different parts of your brain work for different subjects. Bruckner says that to maintain a healthy mind-body-spirit temperament in the heat of exam season, sit down with your calendar. "Make a schedule for a month—when your assignments are due, when your final exams are, what the weighting is for each," she says.

单选题Professor Smith recently persuaded 35 people, 23 of them women, to keep a diary of all their absent-minded actions for a fortnight. When he came to analyze their embarrassing lapses (差错) in a scientific report, he was surprised to find that nearly all of them fell into a few groupings. Nor did the lapses appear to be entirely random (随机的). One of the women, for instance, on leaving her house for work one morning threw her dog her earrings and tried to fix a dog biscuit on her ear. "The explanation for this is that the brain is like a computer," explains the professor. "People programme themselves to do certain activities regularly. It was the woman's custom every morning to throw her dog two biscuits and then put on her earrings. But somehow the action got reversed in the programme." About one in twenty of the incidents the volunteers reported were these "programme assembly failures". Altogether the volunteers logged 433 unintentional actions that they found themselves doing—an average of twelve each. There appear to be peak periods in the day when we are at our zaniest (荒谬可笑的). These are two hours some time between eight a. m. and noon, between four and six p.m. with a smaller peak between eight and ten p.m. "Among men the peak seems to be when a changeover in brain 'programmes' occurs, as for instance between going to and from work." Women on average reported slightly more lapses—12.5 compared with 10.9 for men probably because they were more reliable reporters. A startling finding of the research is that the absent-minded activity is a hazard of doing things in which we are skilled. Normally, you would expect that skill reduces the number of errors we make. But trying to avoid silly slips by concentrating more could make things a lot worse, even dangerous.
